Study Summary

This study aims to evaluate the benefit of bilateral hearing aid use compared to a unilateral hearing aid. Patients with mild to moderate bilateral hearing loss who are considering the purchase of a commercially available hearing aid will be considered for participation. Eligible participants will be randomized to one of the following treatment arms: (1) a bilateral hearing aid fitting group, and (2) a unilateral hearing aid fitting group.

Primary Outcome

The APHAB score ranges from 1 to 99. The change in APHAB score was calculated as the difference between scores at 3 months and baseline, so the range of possible values for the change score is -98 to 98. A lower APHAB score indicates a better benefit; a negative change score indicates greater benefit at 3 months than at baseline.
